I really want Kang, but what I'm assuming will happen based on various information (rumors + facts that we have:

Movie 1: Loki + Aliens...Loki makes a deal with Thanos and steals the gauntlet for him.
Movie 2: Kree/ Skrull War over the infinite gauntlet. The Skrulls have the gems, and the Kree have somehow gotten a hold of the gauntlet itself. In the end, the Kree win, and Ronan the Accuser comes into possession of the fully powered gauntlet. In a shock, he presents it to his father, Thanos (Thanos is Ronan's father in Ultimate Marvel.)
Movie 3: Infinite War yada yada.
